100+ currencies, including trips in local currency.
Automatic capture
Apple Pay (iOS 18+) and bank notifications (iOS 27) through Shortcuts. Android (coming soon): bank notifications and Google Wallet. No bank passwords, no bank connection.
Ways to split
50/50, a fixed percentage, or by income.
Balance periods
Monthly, twice a month (1st to 15th, 16th to month end) or every two weeks from a payday.
Privacy
Personal expenses in Mine are visible only to their owner and never mixed with shared data. No data selling, no ads.
Money movement
Couplesplit never moves money. Partners transfer from their bank and record the settlement.
Not a fit for
Large groups or roommates (use a group splitter); full net-worth tracking with bank sync (use a full finance app).
